EGG-BEATER'.

SPECIFICATION forming part of Letters Patent No. 632,780, datedSeptember 12, 1899.

Application filed July 23,1898. Serial No. 686,725. (No model.)

To @ZZ whom t 17mg concern.-

Beit known that I, HENRY T. CREPEAU, of Boston, in the county of Suffolkand Commonwealth of Massachusetts, have invented certain new and usefulImprovements in Egg Beaters and Mixers, of which the following is adescription sufficiently full, clear, and exact to enable any personskilled in the art or science to which said invention appertains to makeand use the same, reference being had to the accompanying drawings,forming part of this specification, in which- Figure l is a verticaltransverse section showing my improved egg-beater in position for use,and Fig. 2 a horizontal section on line 2 2 in Fig. 1.

Like letters of reference indicate correspondingparts in both figures ofthe drawings.

Myinvention relates especially to that class of egg-beater whichcomprises a vertically-reciprocating plunger and which may be employedwith an ordinary goblet or similar receptacle, so that it may also beutilized for mixing liquid drinks and materials other than eggs, theobject being to produce a simple, cheap, and effective device of thischaracter.

The nature and operation of the invention may be understood from thefollowing explanation:

In the drawings, A represents an ordinary drinking-glass, in which thebeating mechanism is disposed. This mechanism comprises a piston-rod B,provided at an end with a detachable knob or handle d. This rod is ttedto slide freely through a metallic conical cover C, anged at fto overlapand close the mouth of the receptacle A. On the lower end of the rod Bis fast a concave head or disk g, which is perforate and of a diametersuitable to pass to the bottom of the receptacle. Atasuitable distanceabove the head g on the rod B there is a boss or stop-flange h. A diskz', provided with a hub j, is fitted to slide freely on the rod betweenthe head g and stop h. This disk has radiating spokes la connecting itwith an annular rim p. A spirally-wound spring A encircles this rim.Said spring being thus bent into a circle tends to resume its normalposition, and thus bears radially against the inner edge of the rim.While the diameter of the rim is somewhat less than that of the head g,the diameter of the spring carried thereby is greater than said head, sothat a horizontal or diametrical movement may be imparted as said springengages the Walls of the receptacle.

In the use of my improvement the eggs or other material to be beaten ormixed are placed in the Haring receptacle A. The cover O is thenadjustedthereon and held by one hand of the operator. The plunger Bbeing forced downward, the fora minous head g is projected through thecontents which is cut as it presses through the perforations until saidhead reaches the bottom of the glass. The plunger is rapidlyreciprocated vertically, and the weight or density of the contentscauses the spring bearing-disk j to remain stationary therein untilengaged either by said head or the stop h, which impact blows theretoand then causes said disk to move with the plunger. The spring serves toout and whip the eggs by its additional sidewise or horizontal movementin a manner that will be understood by those conversant with suchmatters.

The action of my device, as described, is very rapid and eective, theforaminous head g imparting a constant vertical llow to the contents,said iioW being cut across by the action of the spring. Moreover, thedisk t, operating above the foraminous plunger-head and between it andthe stop, acts as a whipper, and I nd that in practice it will produceor churn butter from the small quantity of cream the receptacle A willhold in an almost increditably short space of time. I am aware thatplungers for this purpose have been provided with foraminous heads and,

some with a movable body under said head, but such will not and fromtheir construction cannot produce the results I effect. The stop lo mayof course be located at any desired distance above the head g, and theplay of disk i' be thereby regulated. I therefore deem it an essentialfeature of my invention to locate a sliding cutting disk above theforaminous plunger-head and fitted to slide on the plunger-rod.Attention is furthermore called to the fact that at intervals during thetravel of the rod B the disk o' is held stationary in the dense liquidand when contacted either by stop h or head g is carried thereby to beagain left by reciprocation of the rod. This con- IOO stantly disposesitin dierent positions in the contents when the blows are administered andadds materially to its eectiveness.

Having thus explained my invention, what I clailn is- 1. An egg-beatercomprising a plunger-havin ga disk-shaped foralninous head and a stop onits rod; a disk fitted to slide on said rod between its head and saidstop; and a spirally- Wound spring encircling the periphery of saiddisk.

2. In combination the receptacle, A, and cover, C; the plunger fitted toslide in said cover' and provided with the foraminous head and stop; thespoked disk fitted to slide on said rod between its head and stop andthe spirally-Wound spring encircling the riln of said disk substantiallyas and in the manner set forth.

3. In an egg-beater the combinationof a receptacle; a cover closing themouth thereof p
